Class 尝试在轴 2 中部署模块时抛出异常：OS：Linux，Tomcat Version:8
Class cast Exception while trying to deploy the Modules in axis 2 : OS: Linux , Tomcat Version:8
当我尝试启动 tomcat 时，在部署 axis2 模块时，我收到 class 强制转换异常 。
我启用了 EnableChildfirstClassLoading 属性。当我检查 classloading(using -verbose) 时，一些 classes 被加载了两次。
例如[Loaded org.apache.axis2.engine.MessageReceiver from file:/irv_test/cipsm/SecureLinkTestingNEW/SLInstaller1/app4.0/tomcat/webapps/axis2/WEB-INF/lib/axis2-kernel-1.6.2.jar]
此 class 从同一 jar 位置加载两次。
轴版本：1.6.2
Tomcat: 8
OS: 红帽 Linux
跟踪如下：
